I think you might be mistaking Captivate slide fps for the
full-motion fps. Captivate animates slides by a default value of 30
fps (not 10 fps) and that can be changed at "Project >
Preferences > Preferences (tab)".
On the other hand, full-motion video (which I fear you are
using as your "regular" capture mechanism) is fixed and not subject
to user-adjustment. I hope I have understood your question and
addressed it ... but if not, let me know and I'll be happy to try
again if I am missing your point.
